Abstract: The research of the core concrete's empty which influences the mechanics performance of concrete filled steel tube components is a hot issue currently.Aiming at the core concrete's filled status of the concrete filled steel tube arch bridge which has been on operation for six years in southwest,through the similitude model trials and theoretic analysis,the core concrete's empty influence on the mechanics performance of concrete filled steel tube components is briefly introduced.It offers referces to the design,construction and examination of this kind of bridge.

Key words: core concrete, empty, concrete filled steel tube components, mechanical performance, influence
